Marty,

This does not answer your question but I made an indexer from scratch. The indexer is made
in two pieces so gear clearance can be precision ground to minimise clearance and backlash.

Made of castiron and 30:1 gears purchased on Ebay. Didn't cost that much to make.

So much to learn and so little time.

I guess since I have both and all that is involved would be a DC servo motor, maybe I will do the rotab first.

FYI, I happened into a HAAS 5C indexer for a good price, so I went with it. :-)
